Electrical Power Formulas Used in ABB Calculator
This tool is based on standard electrical engineering formulas used in AC circuits.
1. Real Power (W)
Where:
- P = Real Power (Watts)
- V = Voltage (Volts)
- I = Current (Amperes)
- PF = Power Factor
2. Active Power (kW)
This converts watts into kilowatts for easier interpretation.
3. Apparent Power (kVA)
Where:
- S = Apparent Power (kVA)
Understanding Power Factor
Power factor is a crucial concept in electrical systems. It represents how efficiently electrical power is being used.
Power Factor Range:
- 1.0 → Perfect efficiency
- 0.8–0.95 → Good industrial systems
- Below 0.7 → Poor efficiency
Why Power Factor Matters:
- Impacts electricity bills
- Affects system efficiency
- Determines energy losses
A lower power factor means more current is required to deliver the same amount of useful power.
Example Calculation
Let’s assume:
- Voltage = 230V
- Current = 10A
- Power Factor = 0.85
Step 1: Real Power
P = 230 × 10 × 0.85 = 1955 W
Step 2: Active Power (kW)
1955 ÷ 1000 = 1.955 kW
Step 3: Apparent Power (kVA)
(230 × 10) ÷ 1000 = 2.3 kVA
Example Calculation Table
| Voltage (V) | Current (A) | Power Factor | Real Power (W) | Power (kW) | Apparent Power (kVA) |
|---|---|---|---|---|---|
| 230 | 5 | 0.9 | 1035 | 1.04 | 1.15 |
| 230 | 10 | 0.85 | 1955 | 1.96 | 2.30 |
| 230 | 15 | 0.8 | 2760 | 2.76 | 3.45 |
| 415 | 10 | 0.9 | 3735 | 3.74 | 4.15 |
| 415 | 20 | 0.85 | 7070 | 7.07 | 8.30 |
